Production methods and plating of the plated

The present invention is a plated appearance is good metallic layer is formed on the surface of the substrate, with a small number of steps, and aims to provide a method capable of producing in a short time, the plating of the present invention method for producing things, at least, a step of forming a (1) a substrate on a part or the whole of the surface of (a), by applying a composition containing a polythiophene-based conductive polymer, a conductive polymer layer (B), ( 2) by depositing a metal catalyst on the conductive polymer layer (B), the step of forming a conductive polymer layer containing a metal catalyst and (C), and, on (3) the conductive polymer layer (C) forming a metal layer (D) by an electroless plating, characterized in that through the.
